Captain James Brennan born Sligo Town died Watsonville, CA

I grew up on Brennan St and I am trying to locate more information about the person the street was named after. James Brennan was born in Sligo Town, Co. Sligo in 1823. He came to the U.S.in the late 1840s. He was partner with Captain Sudden in a steamship company that transported produce from the Pajaro Valley to San Francisco. In the 1870 Census he and two sisters, Margaret and Ann are listed. Margaret & James are buried in Watsonville and I assume his sister Ann married but I don't know. He came to the U.S. from Quebec. Hopefully this family sounds familiar.Thank you,Margaret Kristich
